Flat plug

Abstract

A flat plug includes a base body having a first and a second end, a terminal part integrally connected to the first end of the base body, and a contact blade having two blade halves integrally connected to the second end of the base body. The two blade halves have a broad side, an outer contour and a longitudinal axis. The blade halves are mutually symmetrical about the longitudinal axis with respect to the outer contour. Additionally, the broad side of the two blade halves rest flat against one another in a folded state, whereas the two blade halves are spaced apart from one another along the longitudinal axis in an unfolded state.

We claim: 
     
       1. A flat plug, comprising: a base body having a first end, a second end and a width;   said base body having a v-shaped cross-section in a folded state;   a terminal part having terminal ribs integrally connected to said first end of said base body, said terminal ribs having a given width less than said width of said base body; and   a contact blade having two blade halves, each of said two blade halves having a neck with a given width less than said width of said base body and integrally connected to said second end of said base body,   said two blade halves having a longitudinal axis and an outer contour, said blade halves being mutually symmetrical about said longitudinal axis with respect to said outer contour, said longitudinal axis defining a single folding line for folding the flat plug into the folded state;   each of said two blade halves having a broad side,   said broad side of said two blade halves resting flat against one another in the folded state, and said two blade halves being spaced apart from one another along the longitudinal axis in an unfolded state.   
     
     
       2. The flat plug according to claim 1, wherein each of said two blade halves is symmetrical defining center lines extending parallel to the longitudinal axis. 
     
     
       3. The flat plug according to claim 1, wherein each of said two blade halves includes a remaining portion connected to said neck, each of said necks being narrower than each of said remaining portions. 
     
     
       4. The flat plug according to claim 1, wherein said base body is disposed symmetrically about the longitudinal axis. 
     
     
       5. The flat plug according to claim 1, wherein said base body includes base body halves, at least one of said base body halves having at least one detent element disposed thereon. 
     
     
       6. The flat plug according to claim 5, wherein said at least one detent element is two detent elements extending outwardly on said base body halves, said detent elements being tabs formed by U-shaped notches in said base body being bent outward.   
     
     
       7. The flat plug according to claim 5, wherein said at least one detent element is two detent elements extending outwardly on said base body halves, said detent elements being tabs formed by U-shaped notches in said base body being bent outward.   
     
     
       8. The flat plug according to claim 5, wherein said at least one detent element is two detent elements extending outwardly on said base body halves, said detent elements being tabs formed by V-shaped notches in said base body being bent outward.   
     
     
       9. The flat plug according to claim 1, wherein said contact blade, said base body and said terminal part are constructed from a metal strip. 
     
     
       10. The flat plug according to claim 1, wherein said base body, in the unfolded state, has a quadrilateral outer shape with four outer edges, two of said outer edges extending parallel to the longitudinal axis, and two of said outer edges extending orthogonally to the longitudinal axis. 
     
     
       11. The flat plug according to claim 1, wherein said two blade halves are adhesively connected in the folded state. 
     
     
       12. The flat plug according to claim 1, wherein said two blade halves are soldered together in the folded state. 
     
     
       13. The flat plug according to claim 1, wherein said two blade halves are welded together in the folded state. 
     
     
       14. The flat plug according to claim 1, wherein one of said blade halves has a retaining arm clamping said two blade halves together by engaging in the other of said blade halves. 
     
     
       15. The flat plug according to claim 14, wherein said other blade half has a first tab disposed thereon; said one blade half has an edge; and   said retaining arm is a second tab being attached to said edge, being back 180° toward said one blade half and being engaged by said first tab, defining flush surfaces of said contact blade.   
     
     
       16. The flat plug according to claim 1, wherein said one blade half has at least one bead formed thereon and said other blade half has at least one bore formed therein corresponding to said at least one bead, said at least one bead being pressed into said at least one bore in the folded state to join said two blade halves.
